Concrete/Asphalt Blade - 300DPA/C. Testing has been taking place at Duro with various new types of synthetic diamond grit from DeBeers. The new grits are especially designed with a high impact resistance but also with free cutting properties, to try and solve the age old problem of developing one diamond cutting blade, for use on both concrete and asphalt applications. The problems have always been that blades of this nature either cut quickly but also wear out quickly, when used in asphalt or alternately, last a reasonable time in asphalt but are too hard for continued use in concrete. As a result, users generally continue to use 2 specifications, 1 for each application. That is now a thing of the past with, the new 300DPA/C.
Blades for concrete are generally designed with cobalt bond systems, narrow gullets, tall segments and no undercutting protection, as it's not required, whereas asphalt blades are made with high tungsten and carbide containing bond systems, use wide gullets, have undercutting protection and relatively low segment heights. So the conflict in design is clear. The new approach taken by Duro has been to compromise the blades design by keeping narrow gullets, adding in undercutting protection and then creating a totally new bond system which has free cutting properties but is able to retain each individual diamond grain for much longer. Combining this with the new DeBeers grit, this blade is a complete success.
Design Features Include:
• Wide gullet core design
• Tall 10mm segment height
• Drop segment undercut protection (350mm only)
• Laser welded segments
• DeBeers diamond (4 grit sizes)
• Patent pending metal bond system
• EN13236, oSa, ISO9001
• Laser etched core (inc serial numbers, application data, safety data etc)
• 20mm bore (300mm)
The new blades from Duro are leading the way in Dual Application technology! The blades are designed for use on all concrete materials including reinforced concrete as well as Asphalt and abrasive materials.
